Curation Score

This skill scores 68/100, which means it is acceptable for directory listing but best suited for users already adopting Rube MCP/Composio. It gives agents enough setup and trigger guidance to start VirusTotal automation with less guesswork than a generic prompt, but its value is limited by reliance on live tool discovery and relatively thin VirusTotal-specific workflow detail.

68/100

Strengths

Clear trigger and scope: automates VirusTotal operations through Composio's VirusTotal toolkit via Rube MCP.
Operational prerequisites are explicit, including RUBE_SEARCH_TOOLS availability, RUBE_MANAGE_CONNECTIONS, and confirming an ACTIVE VirusTotal connection before workflows.
Includes a repeatable discovery-first workflow pattern with example RUBE_SEARCH_TOOLS calls, reducing schema guesswork for agents.

Cautions

Depends entirely on Rube MCP and an active VirusTotal connection; there are no bundled scripts, reference files, or standalone implementation assets.
Workflow guidance is mostly generic tool-discovery/setup pattern rather than detailed VirusTotal-specific playbooks, so agents may still need to infer task-specific execution after schema discovery.

Overview

Overview of virustotal-automation skill

What virustotal-automation does

virustotal-automation is a Claude skill for running VirusTotal workflows through Composio’s Rube MCP server. Instead of hard-coding VirusTotal API calls, the skill teaches the agent to discover the current Composio VirusTotal tools first, verify the connection, inspect the returned schemas, and then execute the correct action with validated inputs.

This is useful when you want an AI agent to help with file, URL, domain, IP, or hash investigation while staying aligned with the live tool interface exposed by Rube MCP.

Best fit for Threat Intelligence workflows

The strongest fit is virustotal-automation for Threat Intelligence: malware triage, indicator enrichment, suspicious URL review, domain/IP reputation checks, and repeatable security-analysis workflows where the agent needs to call real tools rather than only reason from text.

It is especially relevant for analysts who already use Claude with MCP and want a safer pattern for VirusTotal automation: discover tools, confirm authentication, execute, then summarize findings with the original indicators and tool outputs separated from interpretation.

What makes this skill different

The main differentiator is the “search tools first” rule. Composio tool schemas can change, so the skill does not assume fixed function names or inputs. It instructs the agent to call RUBE_SEARCH_TOOLS before using VirusTotal actions, then use the returned schema and execution plan.

That makes the virustotal-automation skill more robust than a generic prompt such as “check this hash on VirusTotal,” because it includes connection checks, schema discovery, and a repeatable workflow pattern.

Important adoption requirements

This skill requires Rube MCP and an active VirusTotal connection through Composio. If your client cannot access MCP tools, or if you need direct standalone Python scripts, this repository will not provide that. The upstream package contains a single SKILL.md; there are no helper scripts, references, or local automation files to run outside the MCP environment.

How to Use virustotal-automation skill

virustotal-automation install context

Install the skill from the Composio skills repository:

npx skills add ComposioHQ/awesome-claude-skills --skill virustotal-automation

Then configure Rube MCP in your AI client by adding:

https://rube.app/mcp

Before expecting the skill to work, confirm that the MCP tool RUBE_SEARCH_TOOLS is available. Next, use RUBE_MANAGE_CONNECTIONS with toolkit virustotal and complete the returned authentication flow if the connection is not ACTIVE.

Inputs the skill needs to work well

For useful virustotal-automation usage, provide the indicator type, the exact indicator value, the goal, and the output format you need. A weak prompt is:

“Check this suspicious thing on VirusTotal.”

A stronger prompt is:

“Use virustotal-automation to investigate this SHA-256 hash: .... First discover the current VirusTotal tools through Rube, confirm the VirusTotal connection is active, then retrieve relevant reputation/detection information. Summarize detections, notable vendor labels, timestamps if available, and confidence. Do not invent results not returned by the tool.”

For multiple indicators, specify whether you want batch processing, prioritization, or one report per IOC.

Practical workflow for real investigations

A reliable virustotal-automation guide workflow is:

Ask the agent to call RUBE_SEARCH_TOOLS for the specific task, such as “VirusTotal hash lookup” or “VirusTotal URL analysis.”
Have it inspect the returned tool slug, required fields, and known pitfalls.
Confirm the VirusTotal connection status with RUBE_MANAGE_CONNECTIONS.
Execute the chosen VirusTotal tool with the exact schema returned by discovery.
Ask for a structured report that separates raw tool output from analyst interpretation.

This matters because VirusTotal-style enrichment can include ambiguous signals. A low detection count, old scan timestamp, or missing object should not be over-interpreted without context.

Repository files to read first

The repository path is composio-skills/virustotal-automation, and the important file is SKILL.md. Read it for prerequisites, setup, tool discovery, and the core workflow pattern. There are no bundled scripts/, references/, resources/, or README.md files in this skill, so adoption depends on your MCP setup and the live Composio VirusTotal toolkit documentation at composio.dev/toolkits/virustotal.

virustotal-automation skill FAQ

Is virustotal-automation enough without Rube MCP?

No. The skill is designed around Rube MCP and Composio tool calls. Without RUBE_SEARCH_TOOLS and RUBE_MANAGE_CONNECTIONS, the agent can still explain a VirusTotal workflow, but it cannot execute the intended automation path.

How is this better than an ordinary Claude prompt?

An ordinary prompt may produce a plausible investigation plan but will not know the current Composio tool schemas. virustotal-automation explicitly tells the agent to discover live tools first, verify the VirusTotal connection, and use the schema returned by Rube. That reduces broken calls and hallucinated parameters.

Is this suitable for beginners?

Yes, if the beginner is comfortable setting up MCP connections. The skill is short and focused, but it assumes you understand what an IOC is and why VirusTotal results need interpretation. New users should start with a single hash, URL, domain, or IP before attempting batch enrichment.

When should I not use this skill?

Do not use it if you need offline malware analysis, sandbox detonation outside VirusTotal, direct API client code, or SIEM/SOAR playbooks packaged as scripts. The skill is a Claude/MCP orchestration guide, not a full threat-intelligence platform.

How to Improve virustotal-automation skill

Improve virustotal-automation prompts

You will get better results by giving the agent a complete investigation contract. Include:

Indicator type and exact value
Desired VirusTotal action, such as lookup, enrichment, or report summary
Whether to use only tool-returned evidence
Required output format, such as table, JSON, or analyst note
Any environment limits, such as “do not submit files” or “lookup only”

This helps the skill choose the right discovered tool and prevents the agent from blending real results with generic threat-intelligence advice.

Common failure modes to watch

The most common issue is skipping RUBE_SEARCH_TOOLS. If the agent assumes a tool name or input schema, stop it and ask it to rediscover the current VirusTotal tools. Another common issue is proceeding before the connection is ACTIVE; the correct fix is to run RUBE_MANAGE_CONNECTIONS and complete the auth flow.

Also watch for overconfident summaries. VirusTotal results are evidence, not final attribution. Ask the agent to label uncertainty and preserve raw fields when they affect the conclusion.

Stronger outputs after the first run

After the first output, iterate with targeted follow-ups:

“Show which claims came directly from VirusTotal output.”
“List missing data that would change the confidence level.”
“Compare these indicators and group related infrastructure.”
“Return a concise SOC handoff with IOCs, severity, and recommended next action.”

These prompts improve decision quality because they turn a basic lookup into an operational security artifact.

Good contribution ideas

The upstream skill would be stronger with example prompts for hash, URL, domain, and IP workflows; a short troubleshooting section for inactive connections; and sample report formats for threat-intelligence teams. If you extend virustotal-automation, keep the core rule intact: discover current Rube tool schemas first, then execute.
